Wall Opening Requirements When roughing in the opening for the wall sleeve, make certain there is sufficient clearance from the walls and floor. The wall sleeve should be positioned a minimum of 1-5/8" in from the room side finished wall to accommodate the the hydronic heat section and room cabinet. A minimum distance of 3" above the finished floor is required for return air, although when using a louver frame in panel wall or thin wall construction, the opening must start 4" above the finished floor (including carpeting) to provide proper return air. Louver frames should be used for panel wall and thin wall applications to assure positive anchoring to the wall (See Figure 2 on page 4). When using a louver frame, the opening must measure 16-5/8" 42-5/8". The rough opening for the wall sleeve should measure 16-1/4" high 42-1/4" wide. Before installing the unit, check the wall opening to be sure the wall sleeve will slide into the opening unobstructed and there is allowance for a 1/8" to 1/4" pitch inside to outside for proper sleeve drainage. For masonry walls, a lintel must be used to provide support over each opening.

When using a louver frame, the opening must measure 16-5/8" 42-5/8". The opening must start 4" above the finished floor (including carpeting) to provide proper return air. The louver frame must be installed prior to, or at the same time, as the wall sleeve, and it must be level and square. 1. Apply caulking compound on the surfaces of the louver frame s four flanges which will come in contact with the wall. Add caulking as required for weather tight seal. 2. Insert the sleeve of the louver frame into the wall opening from the exterior of the building and apply firm pressure so that the caulked frame flanges are snug against the exterior of the building. Secure the louver frame to the wall if desired. 3. Secure the louver frame to the wall through the sides and top. Never secure the frame through the bottom as it may cause leaks. If the louver frame is to be installed in a panel wall, it should be installed at the same time as the wall sleeve / 4 " Wide Cabinet/ Rough Opening DO NOT drill holes in the bottom of the wall sleeve as it will cause leaks.

Flange is factory welded at given dimension when option is designated. Installation of wall sleeves with continuous louvers is very similar to that of applications with factory furnished louvers. Assuming the louver meets Daikin s criteria, as stated previously, proceed to install the wall sleeve as follows: 1. Clean the opening of all debris that may interfere with installation. 2. Position the wall sleeve into the wall so that it is flush with the exterior wall. Important: If the wall sleeve is installed into a thick wall it should be recessed 1-1/4", or as required from the face of the exterior brick, so when the louver is installed it is flush with the exterior face of the building. The wall sleeve must protrude into the room a minimum of 1-5/8" (29mm) beyond the finished interior wall surface, to accommodate the heat section and room cabinet. The center of gravity is 10-3/4" (273mm) from the rear face of the standard wall sleeve. If no subbase is being employed, adequate support for the wall sleeve up to the center of gravity must be provided at the job site. This support can be wood, metal or concrete. 3. Level wall sleeve side to side and pitch to outside 1/8"/ft. to assure proper sleeve drainage to outside. Anchor with appropriate fasteners using holes provided (see Figure 12 on page 8), or drill additional holes as required to secure firmly. Do not drill holes in the base of the wall sleeve. Use shims between the wall and the wall sleeve to prevent wall sleeve distortion during anchoring. 4. Caulk the wall sleeve to the wall opening on both the inside and outside perimeter. This can be done from the inside of the building. Be careful not to plug the weep holes. IM 1196 / Page 5 of 8

7 Installing Thick Wall Construction Installing Extension A wall sleeve extensions is typically used in thick wall construction. The extension is shipped in a separate carton and tagged to match the proper unit. Be sure to check tagging of the extension against that of the unit. Install the wall sleeve extension as follows: 1. Position the extension with standard wall sleeve so proper alignment with drain and mounting holes is achieved. 2. Place a bead of caulk around the perimeter of the wall sleeve and another bead around the mating side of the wall sleeve extension so that the joint is watertight. Do not permit caulking to block the weep holes. Be sure to use a resilient caulking such as silicone. 3. Assemble the wall sleeve extension to the wall sleeve. Clean out weep holes to assure proper drainage. Figure 9: Wall sleeve extension As Required 9 9 / 16 " Air Splitters 24 5 / Room Side heat section and room cabinet. Be sure to recess the wall sleeve enough to accommodate outside louver. This recess is 3/8" (9.5mm) for stamped louvers and 1-1 4" (32mm) for architectural louvers. The louver should be flush to exterior surface when completed. 4. If a brickstop is employed (as shown in Figure 11), slide the wall sleeve into the wall until the brickstop contacts the exterior bricks, as illustrated in Figure 10. If a brickstop is not used, slide the wall sleeve in the wall so that it extends into the room a minimum of 1-5 8" (41mm) beyond the finished interior wall surface. This allows room to attach the heat section and room cabinet. The wall sleeve should also be recessed enough to accommodate the outside louver. Level wall sleeve side to side and pitch to outside 1/8"/ft. to assure proper sleeve drainage to outside. 5. After the mortar has dried, remove the masonry support from the wall sleeve. Note: The wall sleeve is not intended to replace the lintel. 6. Anchor with appropriate fasteners (as shown in Figure 12 on page 8). A 5/ (8mm) hole is provided on each side, 2" (51mm) down from the top and 2" (51mm) in from the rear of the wall sleeve. It may necessary to drill additional holes in the wall sleeve to firmly secure it. 7. Caulk the wall sleeve to the wall opening on both the inside and outside perimeter using a resilient, nonhardening caulk such as silicone. Be careful not to plug the weep holes. Figure 10: Wall sleeve installation using brickstops 42" 24 5 / B Wood Stool 6 1 / 8 " Extension A heavy-gauge, corrosion resistant wall sleeve is provided for each unit. The wall sleeve is either shipped in a separate carton or shipped in a multi-pack of 15. Typical installation for masonry walls is shown in Figure 10. The recommended installation procedure for this type of construction is as follows: 1. Clean the opening of all debris that may interfere with installation. 2. Be sure the unit s center of gravity falls within the load bearing surface of the wall. The center of gravity for the unit is approximately " (273mm) from the rear edge of the wall sleeve. If the center of gravity is not within the load bearing surface, then additional support such as wood, metal or concrete must be provided in the field. 3. Place a thin pad of soft mortar on the bottom of the opening.
